# create_event write

Create a calendar event and return the created event details for timed or all-day events with attendees and location.

event, RFC 3339 triggers a timed event.

Parameters:
    calendar_id: Calendar ID (default 'primary')
    summary: Event title (required)
    start: RFC 3339 dateTime or YYYY-MM-DD for all-day (required)
    end: RFC 3339 dateTime or YYYY-MM-DD, exclusive end for all-day (required)
    description: Event description (optional)
    location: Event location (optional)
    attendees: List of attendee email addresses (optional)
    send_updates: Notification preference - 'all', 'externalOnly', 'none' (default 'all')
    recurrence: List of RRULE strings (optional, requires timezone)
    reminders: Custom reminders object (optional)
    timezone: IANA timezone (required for recurring events, optional otherwise)
    conference: Auto-generate a Google Meet link (default false)
    visibility: 'default', 'public', 'private', 'confidential' (default 'default')
    transparency: 'opaque' (blocks time) or 'transparent' (default 'opaque')
    color_id: Event color ID 1-11 from get_calendar_colors (optional)

Returns:
    CreateEventResult with:
    - event: Created event object with id, htmlLink, conference data, etc.

Notes:
    - send_updates defaults to 'all' -- confirm with user before creating events with attendees
    - When conference=true, creates a Google Meet conference and returns the join URI

# find_free_busy read

time_min string Yes Start of time range (RFC 3339)
time_max string Yes End of time range (RFC 3339)

# find_open_slots read

Find available meeting times that work for all participants.

Full description 
Find available meeting times that work for all participants.

This is a Toolforest convenience tool (not a Google API endpoint). It calls

error-prone timezone math in the LLM.

Parameters:
    calendar_ids: List of calendar IDs to check availability across (required)
    time_min: Start of search range, RFC 3339 (required)
    time_max: End of search range, RFC 3339 (required)
    duration_minutes: Required meeting duration in minutes (required)
    timezone: IANA timezone for display and working hours (optional)
    working_hours_only: Restrict to 9am-5pm in the specified timezone (default true)
    max_suggestions: Maximum number of time slots to suggest (default 5)

Returns:
    FindOpenSlotsResult with:
    - slots: List of available time slots with start/end
    - calendarsChecked: List of calendar IDs that were checked
    - searchRange: The time range that was searched

Notes:
    - Working hours default to 9am-5pm in the specified timezone
    - Returns empty slots array if no common availability exists
Parameter Type Required Description
calendar_ids array<string> Yes List of calendar IDs to check availability across
time_min string Yes Start of search range (RFC 3339)
time_max string Yes End of search range (RFC 3339)
duration_minutes integer Yes Required meeting duration in minutes
timezone string | null No IANA timezone for display
working_hours_only boolean No Restrict suggestions to 9am-5pm Default: true
max_suggestions integer No Maximum number of time slots to suggest Default: 5

# get_event read

Read a specific event and return full event details, including description, recurrence, reminders, attachments, and conferencing.

Full description 
Get full details of a specific event by ID.

Returns the complete event including full description (no truncation),
conference data, recurrence rules, reminders, and attachments.

Parameters:
    calendar_id: Calendar ID (default 'primary')
    event_id: Event ID from search_events response (required)

Returns:
    GetEventResult with:
    - event: Full event object with all fields

Notes:
    - Returns full description (no truncation, unlike search_events)
    - For recurring events, 'recurrence' contains RRULE strings on the master
    - Instance events have 'recurringEventId' pointing to the master
Parameter Type Required Description
calendar_id string No Calendar ID Default: "primary"
event_id string Yes Event ID
account string | null No Optional Google account override (email). Pass the same account used to fetch this event_id from search_events — event and calendar IDs are scoped to the account they came from, so calling get_event with the default account when the ID was obtained from a non-default account returns "not found".

# list_accounts read

List the Google accounts the user has connected for Google Calendar. Returns each account's email, name, and whether it's the current default for this MCP client. Use when the user mentions "my work calendar" / "my personal calendar" or asks which accounts are available — then pass `account=<email>` to target a non-default account on Calendar tools. `account=<email>` is supported on all Google Calendar tools.

Full description 
Return the user's connected Google accounts for the current MCP client.

Returns:
    ListAccountsResult with one entry per connected Google account, including the
    account's email, display name (when available), and a boolean flag indicating
    which account is the current default for this user + MCP client.

When the user has multiple Google accounts connected, this tool is the canonical
way to discover what's available before invoking other Google Calendar tools with
an explicit `account=...` override.

No parameters.

# update_event_instance write

Update a single instance of a recurring Google Calendar event.

Full description 
Update a single instance of a recurring event.

Use this instead of update_event when you want to modify just one occurrence
(e.g., 'move just this week's standup to 3pm'). The master event remains unchanged.

Parameters:
    Same as update_event. The event_id must be an instance ID
    (format: {master_id}_{YYYYMMDDTHHMMSSZ}) from search_events with
    single_events=true.

Returns:
    UpdateEventInstanceResult with the updated instance event object

Notes:
    - Instance IDs have the format {master_id}_{YYYYMMDDTHHMMSSZ}
    - Modifying an instance creates an 'exception' in the recurring event

event_id string Yes Instance ID (format: {master_id}_{YYYYMMDDTHHMMSSZ})
summary string | null No New event title
